EXTENSION-TABLE.

SPECIFICATION farming par@ of Letters Patent No. 623,062, cated April 1i, 189e.

Application filed March 26, 1898.

Serial No. 675,297. (No model.)

To @ZZ whom it may concern:

Be it known that I, NATHAN ALPERIN, a citizen of the United States,and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Extension-Tables; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specifica-` tion.

Figure l of the drawings is a plan view of a table embodying my invention. Fig. 2 is a longitudinal section with one of the leaves eX- tended an'd the other one partially extended. Fig. 3 is a front elevation of .the upper portion of the table with the leaves innen-extended positions. Fig. 4 is a transverse vertical section.v Figs. 5 and 6 are detail perspective views showing one of the corner-joints.

This invention is designed to provide an extension-table of improved character; and it consists in the novel construction and coinbination of parts, all as hereinafter described, and pointed out in the appended claim.

Referring to the accompanying drawings, the letter A designates the rectangular frame of the table supported upon the legs B.

C designates the central or non-extensible portion of the table-top, and D D the two exi These leaves are secured to strips or cleats D', which are arranged to slide in guides d on the end rails of the table-frame. Said strips or cleats are formed with theincliued upper edge portions at their inner ends and with the similarly-inclined lower edges at their outer end portions.

E is a fixed bar or strip which extends centrally across .the frame A, underneath the top portieri C, or top, asit will hereinafter be termed. Secured to the underside of the table, over said strips, are plates F,each of which carries a depending bolt G,Which projects loosely through an opening in the said bar or strip E. Connected to the lower end of each of said bolts is one end of a helical spring H, whose lower end is seated upon and secured to the head of a bolt h, which is secured in a second bar or strip H' of the frame. Two of these springs are usually employed and they are preferably of the form shown-that is to say, 'of increasing diameters from their bases upward. The bolts 71 are secured by nuts h', and by adjust-ing these nuts the tension ot' the springs may be changed.

In their normal or non-extended positions the two extension-leaves D lie underneath the non-extensible top C, with their inner edges abutting the bar or strips E, said top C being thereby raised and the springs put under tension. outward,the inclined outer end portionsof its bars or strips D', riding on the guides d, `(the inclined innerend portions of said cleats riding underneath the bar or strip'E,) raise the said leaves somewhat and also the top C, thereby putting the springs II under greater tension, until the inner edges of the leaves pass the outer edges of the top. The springs then immediately act to pull the top downward to the plane of the leaves to form therewith an extended level-top table. To restore the leaves to the original positions, the top C is raised sufficiently at its ends to permit the leaves to ride thereunder. The bars or cleats D' are provided with stops d tolimit the outward movement of the leaves.

It is desired to avoid the use of all square corners in the table in both extended and non-extended positions and to providethe table with rounded corners, which give the table a more ornamental appearance and are also less obstructive. To this end Ironnd the four corners of the top C by cutting the same away in such a manner as to form the shoulders p. The outer corners of the two leaves are rounded in a similar manner, as shown at l. The two inner cornersof `each leaf I provide with an extension M, having an arcuate concave portion m, adapted to fit neatly the convex cut-away portion of the top, and with shoulders m' at .each end thereof to t the respective shouldersp. In order to avoid these corner-ttings splitting or breaking away, I fit the top C and the leaves D D with end strips N, the grain of which runs atright angles to that of the body of said top and leaves. The corner-fittings are made partly in these strips and partly in the body Vhen the'said leaves are pulled portions, as shown. This construction also prevents warping and twisting of the top and leaves, and in the more expensive lines of tables may be used to give a more ornamen- `tal effect by the use of Vdifferent woods.

In order to accommodate the corner eXtensions M when the leaves are in non-extended positions, I form the bar or strip E with rounded end portions E' to fit the concavities m and with shoulders e to dt the inner shoulders m. The provision of these corner-fittings also largely increases the strength and rigidity of the table both in its extended and non-extended positions, since they afford a bracing-bearing for the leaves against lateral movement or vibration. The shape of `these iittings, whereby the interitting or abutting` shoulders m', p, and e are provided, not only largely assists in this increase of rigidity, but it also obviates the use of points or reduced itting portions, such as are easily split or broken off.

It will be seen that the construction above described provides an extension-table of simple and practical character and of ornamental appearance, which has less seams or joints in the top than is required in those tables which have insertible leaves, and one which does away with the necessity for separate storage of the leaves when not in use.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is-

An extension-table having a verticallymovable top whose corners are cut away and formed vWith incnt rounded portions terminating in shoulders, a bar extending transversely and centrally underneath the said top and having conveXed and shouldered end portions, and leaves arranged to slide underneath the said topvfrom opposite1 sides, and having concaved inner corners adapted to fit neatly either the incut rounded corner portions of the top, or the conveXed and shouldered end portions of said bar, the outer corners of said leaves being formed with incut rounded portions which correspond to the corner portions of the top, and register therewith when the leaves are in non-extended position, sub stantially as specified.

In testimony whereof I aflix my signature in presence of two Witnesses.
